NOVELTY - High-flux graphene-metal composite comprises metal wire, outside of metal wire is coated with graphite, metal wire formed threedimensional macroscopic body crimp or the three-dimensional processing has 90-95% of porosity. USE - High-flux graphene-metal composite. ADVANTAGE - The high-flux graphene-metal composite is cost-effective, has absorb a large amount of oil, the macroscopic volume change is not obvious, absorb the trace organic matter in waste water, and has low regeneration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high-flux graphene-metal composite, which involves: (A) adding certain temperature and pressure, carbon-containing process gas, crackng carbon-containing process gas to form a dense graphene layer on surface of metal mesh, stopping the reaction, taking out graphene-metal screen, rolling to form coaxial parallel columnar structure or the metal mesh to form mesh layer in staggered arrangement of the cylindrical structure; (B) forming the metal mesh by crimping coaxial parallel columnar structure or the metal mesh to form mesh layer in staggered arrangement of the cylindrical structure; and (C) placing metal wire mesh structural member in the reactor under a certain temperature and pressure, adding carbon-containing process gas, cracking carbon-containing process gas metal mesh surface to form a dense graphene layer, stopping the reaction to obtain final product.
